Avoidance or responsible moral choices -- what is your supervisor like?

Researchers at the University of Jyväskylä identified four moral identity statuses in Finnish leaders: achieved, foreclosed, diffused, and moratorium. An achieved identity is characterized by a clear, self-chosen value framework, while foreclosed identities are based on adopted values without critical evaluation. The study highlights t...

Artificial chemical DNA switch helps understand epigenetic mechanisms

Researchers developed an artificial chemical DNA switch that can be turned on and off using light, offering a novel approach to epigenetics. The method uses chemical reactions in the major groove of DNA to influence gene switching, potentially leading to targeted regulation of gene expression.

How spin dances with dipole

Researchers have discovered three key paths for coupling magnetism and ferroelectricity, enabling the interaction between spin moments and electric dipoles in solids. This breakthrough has significant implications for materials science and engineering.

Medicine and personal care products may lead to new pollutants in waterways

Researchers at Rutgers University discovered that bacteria in wastewater plants transform commonly used pharmaceuticals and personal care products into new contaminants, which may harm aquatic environments. The study highlights the need for further evaluation of these emerging contaminants and their potential risks to human health.

Two-step path to shrinking worker bee gonads

Researchers used CRISPR/Cas9 to selectively shut off a gene for female development, finding that diet has no effect on gonad size when the gene is turned off. This suggests that a specific genetic program must be switched on to permit nutrient level to affect gonad size.

Unequal pain relief at home for dying patients

A study of 43,000 people who died in England found that only 10% of non-cancer patients received palliative care at home, compared to 66% of cancer patients. Patients who accessed palliative care at home experienced better pain relief, with 66% experiencing good pain relief, similar to those receiving care in a hospice.
